SHUTTLE.

Specification of Letters Patent.

Patented Sept. 28, 1920.

Application filed. March 15, 1920. Serial H0. 365,756.

'7 0 all whom it may concern:

Be it known that I, JAMES citizen of the United States, residing at New Bedford, in the county of Bristol and State of .Massachusetts, have invented certain new and. useful Improvements in Shuttles, of which the following is a specification.

This invention relates to certain new and useful improvements in shuttles and pertains more particularly to a selft hreading shuttle.

The primary object of the invention is H. OLIVER, a

to provide means whereby the shuttle can.

be easily and quickly threaded in a certain and simple manner,.which means will also act to prevent accidental unthreading of the shuttle.

The invention further aims to provide means of simple and economical construction and which can be adapted for either right or left hand shuttles.

Further and other objects will be later set forth and manifested in the course of the following description.

In the drawings Figure 1, is a topplan view of the front end of a shuttle equipped with the present invention:

Fig. 2 is a side elevation, and

ig. 3, is a detail perspective view of the invention.

In proceeding in accordance with the present invention a plate-like body 1. is employed which may be of simple rectangular form as depicted in the drawings. The inner end portion of the body is formed with an eye 2, which has an entrance slot composed of branches 3 and 4, the latter leading through the front side edge of the body. Branch 3 extends at an angle rearwardly of the body or plate 1 while branch 4 is arranged at an acute angle to 3 so as to assure against accidental unthreading of the shuttle.

The outer end portion of the plate 1, is formed with an eye 5 guarded by a curved finger 6 which latter lies opposite to an arm 7 carried by the plate 1. The arm 7 extends beyond the front side of plate 1 and has upper and lower inclined guards 8 on its outer free end. A diagonal kerfor slot 9 is formed in the rear outer corner of plate 1 and receives a metal strip 10 therein, the ends of the strip extending above and below the upper and lower 1 and forming thread guides.

The shuttle has the usual diagonal ton threading slot S which leads downwardly at S into the usual delivery eye. The invention as is apparent is applicable to either a right or left hand delivery by mere reversal of the plate 1, i. 6., turning same upside down or over. Otherwise it is merely necessary to cut the shuttle to receive the plate in the position of Fig. 1, and to form a longitudinal slot 11 to receive arm 7, the slot 11, being deeper than the thickness of the plate as depicted in Fig. 2. The guard 8 it will be noted is located at the lower end of the branch S of the threading slot.

In operation, the thread is placed in slot S and drawn downwardly through branch S, riding up and over guard 8 and since thelorver end of branch S extends below plate 1, the thread passes through slot 4; in the space between guard finger 6 and arm 7 and below the plate in the space between eyes 2 and 5, entering each of the latter. The thread thus passes over the plate, into eye 2, below the plate and thence upwardly through eye 5 and over finger 6 and arm 7 to the usual delivery point or eye. It thus is apparent that the thread is held against accidental disengagement by suction or otherwise, and is confined against movement by an end of strip 10 and one of the guards 8.

hat is claimed is:

1. In a shuttle. 21

faces of plate plate disposed transversely of the shuttle and having a pair of spaced eyes and slots leading from the eyes to the front side edge of the plate, a right angular arm connected to the outer end of the plate and extending beyond the said front side edge of the plate. upper and lower inclined guards on the outer free end of the arm, said plate having an inclined kerf formed in its rear outer corner, and a metal strip in said kerf having its ends extending above and below the plate.-

2. In a shuttle a plate having a pair of spaced eves each having communication with the front side edge of the plate, an arm connected to the outer end of the plate, and thread engaging means borne by the arm and by the plate to limit transverse movement of the thread.

3. In a shuttle, a member having a pair of spaced eyes I other and beneath the plate, an arm borne arm I gaging means toguide the thread transverselyofi the shuttle axis, an arm extending into said space, the other versely of the shuttle by theouter end of the member and means adjacent the arm ends to restrict movement of the thread transversely of the member.

5. Ina shuttle, a plate having spaced eyes, an arm connected to the outer end of the plate and spaced from the adjacent eye, the last named eye having a slot leading eye communicating with thefront side edge of the plate, and thread guard means associated With the 6; Ina shuttle, a plate having thread engaging -.means to guide the thread transaxis, an arm extending along the outer end of the plate and spaced therefrom, and means adjacent the arm ends to restrict movement of the thread.

.7. In a shuttle, a plate having. thread enalong the outer end of the plate and spaced therefrom, so that the thread Will engage over the top face of the arm and means to restrict movement of; the thread longitudinally of the arm.

8. In a shuttle, a plate having spaced eyes communicating with the outer side edge thereo an arm extending at right angles to the plate and spaced from the outer end thereof whereby the thread will pass from one eye to the other beneath the plate and then upwardly and over the top face of the arm, and means onopposite sides of the outer eye to restrict movement of the thread transversely of the plate.

9,. In a shuttle, a member having a pair of spaced eyes tormedto receive the thread and arranged to hold the same in a position wherein the thread extends from one eye to the other and beneath the plate and means cooperating With the outer eye and engaging the thread to hold the thread from movement out of said outer eye.

10. In a shuttle, a plate having thread engaging means to guide the thread transversely of the shuttle axis, and an arm extending along the outer end of the plate and spaced therefrom, so that the thread will engage over the top face of the arm.

In testimony whereof I afiix my signature.

JAMES H; OLIVER.
